Being a long time PSB fan the wait for Fundamental was totally worth it.. I'm still listening to it regularly after almost 2 years since its release. The best song of the whole Fundamental period for me was The Resurrectionist, a b-side from the I'm With Stupid -single.

On the official site there's a good deal of alternative versions to be heard from Fundamental and other good stuff as well if you go to the Product / Exclusive Tracks section.
